So, I am sick of having my PC on 24/7 for torrents, and sick of having to transfer files to various PCs & HTPC's around the house. I want to be able to add drives as I need them (Dynamic Growth?) Leave it on 24/7 for torrents (FreeNAS has the Transmission client?) Have some safety - what if a drive fails? (If I was to do some sort of raid, which should I do, bearing in mind speed is not a primary factor) What is the impact if a file is being accessed by two different sources, ie. same movie being watched by two different HTPC's? Should I buy a ready to go NAS or build one myself? (I have no problem building PC's) Obviously I am a big noob when it comes to this; the only experience I have with RAID was setting up a RAID 0 with Windows XP many years ago for a friend. My only Linux experience was setting up Ubuntu on my HTPC with XBMC, which was only accomplished with a tutorial.
